STEAM GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 31 ,392, dated April21, 1885.

Application filed October 14, 1884. (No model.)

To all whom it may concern:

Be it known that I, EDGAR PENNEY, a citizen of the-United States,residing at Waynesborough, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements in SteamGang-Flows; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to that type of steam gang-plow wherein adiagonal gang of plows is mounted on a separate frame, which frame isconnected with a traction-engine.

My improvement consists of certain combinations of mechanical devices,which combinations are specifically pointed out in the claims at theclose of this specification, and the practical application and modusoperandi of which are clearly set forth in the following detaileddescription, aided by the annexed drawings.

Figure 1 is a plan view showing so much of a steam gang-plow as willsuffice to illustrate the application of my invention. Fig. 2 is a sideelevation of the same.

The same letters of reference indicate identical parts in all thefigures.

The plow-frame consists of a diagonal hitching-beam, A, side beam A,side beam A and cross-beam A The forward ends -of the side beams,forming a fork, are provided with suitable bearings for attachment tothe extension ends of the rear axle of the traction-engine. Thehitching-beam is trussed, substantially as described in my applicationfor United States Patent filed October 14, 1884, Serial No. 145,491. Idisclaim here whatever is claimed in said application. The diagonal rearend of the plow-frame is supported upon the two caster-wheels B and B.In order that these caster-wheels may be of large diameter, while theplow-frame is a comparatively low one, and that said wheels may beranged to run at opposite ends of and substantially abreast with thediagonal rank of plowshares, I provide suitable overhung goose-neckedbrackets, b and b, in which the stocks b and b of the respective wheelsare journaled. The brackets project sufficiently beyond and to the rearof the diagonal hitching-beam to range the wheels with the plowshares,and the goosenecked form of the brackets allows all necessary swing tothe wheels. The upper end of the journal of stock b projecting above itsbracket. has a cross bar, 0, fixed to it, and a similar cross-bar, c, isfixed to the projecting upper end of the journal of stock b Thesecross-bars cand c are-connected by rods 0 and 0 The stocks of the wheelsbeing thus connected, the wheels will always swingin unison. Ahand-wheel, c, is applied to cross-bar c, as shown in Fig. 2, so thatthe plowman may swing the caster-wheels, if necessary, to effect theproper guidance of the machine. Since these wheels are at differentdistances from the traction-engine, they must be turned at differentangles in the turnings of the ma chine. This is approximately effectedby hitching the rods 0 c to one cross-bar at points differing in theirrelation to the axis of the stock from the points where they are hitchedto the other cross-bar,'so that by turning handwheel a one of thecaster-wheels will assume a greater angle than the other. Series ofholes 0 in cross-bare provide for adjustments of one end of rods 0 c forthe purpose of ob taining any required differential dispositions of thecaster-wheels. The cross-bars c and 0 may project in one direction onlyand be connected by a single rod, all as shown in Fig. 2. The collar 1)of each stock is provided with a stop-pin, b, which projects up througha-concentric slot, 12 in the collar b of the bracket,

- so that the swing of the caster-wheels is limited by the play affordedpin 1) in slot b Holes are also bored in the collars b and b", whichregister when the wheels B and B are parallel with the side beams A andA or, in other words, are parallel with the tractionwheels of theengine. Alocking-pin, b", may be used to lock the stock to its bracketwhen the caster-wheels are in' the position just mentioned. Wheel B runson the unplowed ground, while wheel B runs on the plowed ground.

The drawings show only one of the gang of plows; but the positions ofthe others are indicated by broken lines in Fig. 1. Each plow isindependently hitched. It is drawn by a draft-rod, D, the forward end ofwhich is connected either to the plow-frame or to a fixed part of thetraction-engine. The rear end of the draft-rod is forked to embrace afiat strut, a, of the truss of the hitching-beam A, and to receive, inrear of said strut, the end of the plow-beam E, which is pivoted to thefork. The fork of thedraft-rod is of sufficient-length to have free playon the strut a, with which it is connected, however, by a cross-pin, a,which is inserted in one of a vertical series of holes in the strut, andpasses through elongated longitudinal slots d in the respective arms ofthe fork of the draft-rod. It will be observed that the pin a merelyserves to hold the forked end of the draft-rod and forward end of theplow-beam at the required height, and that it has to sustain but a smallfraction, if any, of the strain due to the draft.

v The wheels B and B, running abreast with Y the shares of the diagonalgang of plows, will a practically maintain a uniform depth of furrow inplowing undulating ground, because the rising and falling motions of theplowframe (which affect the pitch of the ploW shares) will bepractically coincident with the passage of the plowshares along theunevennesses which cause these motions.

I claim as my invention p 1 1. The combination, substantially as beforeset forth, of the plow-frame, the diagonal gang of plows hitchedthereto, and the wheels for supporting the rear end of the plow-frame,the said wheels being arranged to run abreast with the plowshares of thediagonal gang of plows.

2. The combination, substantially as before set forth, of thetraction-engine, the plowframe having a forked forward end directlyattached to extension ends of the rear axle of the traction-engine, thediagonal gang'of plows hitched to said plow-frame, and the wheels forsupportingthe rear end of the plow-frame, the said wheels being arrangedto run abreast with the plowshares of the diagonal gang of plows.

3. The combination, substantially as before set forth, of the trussedhitching-beam, a strut thereof providedwith a "ertical series of holes,the draft-rod forked to embrace the strut, and having elongatedlongitudinal slots in the arms of its fork for the passage of a pinsupporting it on the strut, and the plow-beam pivoted to the outer endof the fork of the draft-rod.

In testimony whereof I aflix mysignature in presence of two witnesses. V

EDGAR PEN N EY.
